The DbGroupByExpression type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Aggregates | Gets a DbAggregate list that provides the aggregates to apply. |
![]() | ExpressionKind | Gets the kind of the expression, which indicates the operation of this expression. (Inherited from DbExpression.) |
![]() | Input | Gets the DbGroupExpressionBinding that specifies the input set and provides access to the set element and group element variables. |
![]() | Keys | Gets a DbExpression list that provides grouping keys. |
![]() | ResultType | Gets the type metadata for the result type of the expression. (Inherited from DbExpression.) |
| Name | Description | |
|---|---|---|
![]() | Accept(DbExpressionVisitor) | Implements the visitor pattern for expressions that do not produce a result value. (Overrides DbExpression::Accept(DbExpressionVisitor).) |
![]() | Accept<TResultType>(DbExpressionVisitor<TResultType>) | Implements the visitor pattern for expressions that produce a result value of a specific type. (Inherited from DbExpression.) |
![]() | Accept<TResultType>(DbExpressionVisitor<TResultType>) | Implements the visitor pattern for expressions that produce a result value of a specific type. (Overrides DbExpression::Accept<TResultType>(DbExpressionVisitor<TResultType>).) |
![]() | Equals | Determines whether the specified Object is equal to the current DbExpression instance. (Inherited from DbExpression.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for the type. (Inherited from DbExpression.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
